I bought this book on the basis that it had received two good reviews. It was utter tripe. Had I picked it up in a book shop and flicked through it, I would have returned it to the shelves with a snort of derision.
Having paid for it, I felt compelled to read it to the bitter end notwithstanding that the first few chapters had me groaning with boredom. The writer evidently feels she is a very interesting person (she isn't) and goes on for a long time about how she dated someone who worked in the Queen Mother's household. In fact it is openly known that the vast majority of workers there were gay, and I have no idea why she thinks it is important to go on endlessly about her short-lived non-relationship. Snoresville. The rest of the book is equally dull.
I thought this was a total waste of money, along with Jamie Cat Callan's book "French Women Don't Sleep Alone" which was also terrible.
I'd strongly recommend the following Francophile books: Sarah Turnbull's book "Almost French" if you are looking for a well-written and useful account of being a foreigner living in Paris, and Frederic Fekkai's "A year of style" if you are looking to pick up a little je ne sais quoi.
"Entre Nous: A Woman's Guide to Finding Her Inner French Girl: by Debra Ollivier is also good, and all of the Mireille Guiliano ones, especially "Women, work and the art of savoir faire".
